Qualcomm Snapdragon X (Nuvia/Oryon architecture)

I figured it’s about time to have a dedicated thread for the much anticipated Hamoa chips (based on Nuvia tech), set to release next year. We finally have some rumoured model numbers and specs:


Qualcomm will offer several different processors with different configurations:

  • SC8380/SC8380XP with 12 CPU cores
  • SC8370/SC8370XP with 10 CPU cores
  • SC8350/SC8350XP with 8 CPU cores

SC8380XP (3 configurations):

  • 8 P-cores @ 3.4 GHz + 4 E-cores @ 2.5 GHz & 1.25 GHz Adreno 740 graphics
  • 8 P-cores @ 3.2 GHz + 4 E-cores @ 2.5 GHz & 1.1 GHz Adreno 740 graphics
  • 8 P-cores @ 3 GHz + 4 E-cores @ 2.38 GHz & 1.25 GHz Adreno 740 graphics

SC8370XP (2 configurations):

  • 6 P-cores @ 3.4 GHz + 4 E-cores @ 2.5 GHz & 1.25 GHz Adreno 740 graphics
  • 6 P-cores @ 3.2 GHz + 4 E-cores @ 2.5 GHz & 1.1 GHz Adreno 740 graphics

According to that website, the SC8350XP was under development, but may be canceled before release.

So it looks like first-gen Hamoa CPUs are set to compete at against the M-series Pro chip with similar clocks and similar 4 E-core, scaling P-core config:


For the graphics, the Adreno 740 performs at slightly under around M1 GPU levels:


So overall, we should be getting something competitive with M2 compute, but perhaps weaker graphics, and hopefully a lot cheaper for the Pro/Max equivalent 10/12 core SKUs.

If they don’t repeat the pricing blunder of the early SD830 WOA devices, I could see these chips pushing a small revolution in the thin-and-light Windows PC category.


That should read:

If they don’t repeat the pricing blunder of the early SD830 WOA devices

If you recall, QC launched their “Windows on Snapdragon” initiative several years ahead of Apple’s M1.

Now they have the benefit of hindsight, observing the winning strategy of pricing the base M1/M2 as low as $499, with plenty of opportunity to undercut Apple’s Pro/Max chips.

Surely, even the dumbest executive couldn’t screw this up with the example right in front of them (:crossed_fingers:).


There is no limit to the human ability to be stupid…


Well, then I can only take it as a good sign that they aren’t rushing out the release of Hamoa, no? They did bring in a new CEO, Amon, who very shortly afterwards completed the $1.4B deal for Nuvia.

I see intent here. It’s more calculated than their first attempt. (Plus, @Bronsky is dying here for a proper successor to his Go 3. What other hope to we have?)


You got that right.


I’m not sure that it’s a matter of them not rushing to release, but that they simply can’t get it out there any sooner given the allegedly huge issues they are facing with things like die size, thermals and lets face it, potential IP issues which I guarantee Apple has all of their legal/IP team watching with a magnifying glass.

I also think Qualcomm doesn’t have a lot of choice to do anything else as every analysis I’ve read says that the current Snapdragon design is rapidly running out of headroom.

That being said, I genuinely hope they succeed as the market and users will benefit. It’s just that I think that many are underestimating the size and number of hurdles they face in the hope of an alternative to Apple.

BTW, we hear that the moment that any Nuvia based hardware gets outside of Qualcomm, several ARM vendors (including a graphics card maker and not Apple surprisingly) are going to be ready with IP related lawsuits. TLDR, the legacy of what the Nuvia engineers did for Apple, may also be their biggest anchor.


After years of war and discontent with QC, Timmy is going to be all

You know what they say about payback, and the Nuvia team will be in the crosshairs too. Time to get back some of those exorbitant QC royalties, if not literally shutting them down…

And then comes ARM to defend its IP on behalf of its newly minted corporate shareholders…you know, its their civic duty…lawyers lawyers everywhere, and not a check too big…

PS - wonder how much will be leftover for Intel to chew on for x86 emulation???

You guys…I’m trying to build a little hype here, and everyone is piling on QC.

Well I for one will not be daunted. It could be worse; they could have rushed it out the gate half-baked just to please shareholders for the Q4 sales season. Sure there would be problems, but that’s for Q1-Q2 quarterlies to clean up, and Amon could say he hit all targets for 2023, etc.

Lawsuits never daunted QC either. No, Qualcomm’s going to give it their all for long-term success. Amon’s probably got his entire chair riding on this.

SemiAccurate previously told you about Qualcomm/Nuvia’s Oryon SoC that taped out late last year. What we didn’t tell you about is the projected performance and how it is doing now.

Lets start out by saying that as of mid-year the prospects were positive, the SoC had severe issues but those were expected to be cured with a stepping that was in the oven as of Q2. We will ignore Qualcomm’s veiled promises of Oryon being a laptop and phone part which subtly morphed into just being a laptop part for now, it wasn’t by chance.

As we know by now the SoC is the Nuvia core force welded into the Qualcomm uncore, and that is where many of the problems lie. It is a server core and was always meant to be a server core, not a consumer one. Power management is one of the key differences there, and yes we know about the power management die ala Apple’s Monaco but still aren’t clean on the patent situation some have mentioned to us. In short there are a lot of things you can add to a core late in the game, power management is not one of them.

Back to the story at hand we have the now laptop only Qualcomm Oryon part. The core is fine, it hit performance and power targets more or less, and that is good. If you haven’t heard by now, performance is said to be a little better than an Apple M2 and should debut, err, after Apple’s M3. On a brighter note, power is, umm, well it won’t see phone use this generation but somehow this will be spun into a win.

Back to the core/uncore from two different IP ancestries. This is the cause of the major problems that have been dogging Qualcomm for a while now. As of Q2 the device was, umm, not good but the next stepping is intended to cure everything. It is back so how are things now?

Nice find, Sonic. To give a bit more context, Nuvia was actually working with a very tight per-core power budget, but large total power cap:

Why is Nuvia focusing on this 1W-4.5W per core power envelope?#

I’ll let Nuvia answer this:

All current and future flagship server SoCs are power constrained, very much like mobile SoCs. As core count increases, what is not increasing is the TDP. …The TDP range is 250W — 300W, and the power outside of the CPU can range between 10W — 120W depending upon the workload. Taking into consideration these factors, the amount of power that each CPU can be allocated ranges between 1W — 4.5W when heavily utilized, as is the case in a datacenter environment.

So the major challenge is scaling down the architecture to 8 P-cores and lower. It sounds like they were planning on solving this by integrating four Cortex-A510 E-cores from their Kryo architecture, but ran into issues with the power management system (PMICs).

So this would probably explain why QC is so adamant about manufacturers using Qualcomm PMICs, as earlier noted by @dstrauss.

Yes. to their credit, Qualcomm is trying a genuinely new approach to the whole complex puzzle that is TDP versus cores.

Apple very much has relied on a few performance cores to do most of the work (to good effect in benchmarks) while having possibly the downside of not actively encouraging developers to better balance their apps to use all the aspects of the processor.

And @Marty that’s one of the areas I’m optimistic about Hamoa specifically as it relates to WOA as Windows scheduler (despite my occasional jabs at aspects of it) is far more flexible and accessible to developers, though alas, the number of developers to date that actually have done so usually could be counted on Homer Simpsons right hand.

And, one of the biggest things Qualcomm also needs to overcome is an IOS/A series first approach among app developers that even tried to build WOA native apps.


Do you have any info on the outcome of the 2023 Windows Dev Kit?

These sold out quite quickly, where did all those devs go?

(And why did MS they only do one run? It’s a very nice piece of hardware that I’d still be tempted to get today, and definitely if it refreshed with Hamoa.)


We have one, but have also heard off the record that it was “cancelled” though no explanation as to what that means to anyone.

It’s a decent box, though in the end not any more performant than a Pro 9 5g


So a lot of developers bought it out of curiosity, but didn’t make any apps with it? How bout you guys?

I think they really just need to stay the course if they want any traction—and stop canceling everything!


Love this description.

Only if Homer is missing a few digits…

@Marty, it’s here!


In name only old friend - maybe some meat on them bones later this month, and which year it will birth…

To commemorate, I’ve retitled the topic to the proper (and hopefully final) name.
